Đặc tính kỹ thuật
Model | SG220-26-K9-EU |
Performance | |
Switching capacity and forwarding rate | Capacity in Millions of Packets per Second (mpps) (64-byte packets): 38.69 Switching Capacity in Gigabits per Second (Gbps): 52 |
Jumbo frames | Frame sizes up to 9216 supported |
MAC table | Up to 8192 MAC addresses |
Total system ports | 26 Gigabit Ethernet |
RJ-45 ports | 24 Gigabit Ethernet |
Uplink ports | 2 Gigabit Ethernet combo |
Layer 2 Switching | |
Spanning Tree Protocol (STP) | Standard 802.1d STP support Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default |
Port grouping | Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP): Up to 8 groups, Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation |
VLAN | Support for up to 256 VLANs simultaneously Port-based and 802.1Q tag-based VLANs Management VLAN Guest VLAN |
Auto voice VLAN | Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS |
QinQ VLAN | VLANs transparently cross a service provider network while isolating traffic among customers |
Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) | Protocols for automatically propagating and configuring VLANs in a bridged domain |
Head-Of-Line (HOL) blocking | HOL blocking prevention |
Loopback detection | Loopback detection provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP. |
Automatic Media-Dependent Interface Crossover (MDIX) | Automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed. |
Security | |
ACLs | Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, Differentiated Services Code Point (DSCP)/IP precedence, TCP/UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag Support up to 512 rules |
Port security | Creates the ability to lock source MAC addresses to ports; limits the number of learned MAC addresses |
IEEE 802.1X (authenticator role) | 802.1X: RADIUS authentication; guest VLAN; |
RADIUS, TACACS+ | Supports RADIUS and TACACS authentication; switch functions as a client |
MAC address filtering | Supported |
Storm control | Broadcast, multicast, and unknown unicast |
DoS protection | DOS attack prevention |
STP Bridge Protocol Data Unit (BPDU) Guard | This security mechanism protects the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port |
Spanning Tree Loop Guard | This feature provides additional protection against Layer 2 forwarding loops (STP loops). |
Secure Shell (SSH) Protocol | SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported |
Secure Sockets Layer (SSL) | SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch |
Quality of Service | |
Priority levels | 8 hardware queues |
Scheduling | Strict priority and weighted round-robin (WRR) Queue assignment based on differentiated services code point (DSCP) and class of service (802.1p/CoS) |
Class of service | Port based, 802.1p VLAN priority based, IPv4/v6 IP precedence/type of service (ToS)/DSCP based, Differentiated Services (DiffServ) |
Rate limiting | Ingress policer, per VLAN and per port |
Environmental | |
Dimensions (W x H x D) | 440 x 44 x 201 mm |
Unit weight | 2.81 kg |
Power | 100 to 240V 50 to 60 Hz, internal |
